Christian said this was a known bug and to just click OK. I did so and the sequence continued, skipping obj_129. 130-151 iPTF13dkj 60 18:30 J 1.0 0.65 Offset telescope by +5" N, +5" E to get a slightly different center for repeate of dither sequence. 152-176 iPTF13dkj 60 19:00 J 1.01 0.7 177-201 iPTF13dkj 60 19:32 H 1.03 0.7-0.8 Failed to record 191, as with previous error.

The R=11.4-mag is H=10.0 mag and is saturating Christian engaged active autofocus from WTTM around this frame. Perhaps starting a few earlier.. 347 PTF12iiq 10 23:24 J 1.2 0.7 Oops, changed exposure time too soon, was in middle of sequence 348-357 PTF12iiq 60 23:25 J 1.2 0.7 WTTM autofocus is pretty good so far. I think I would set it 5 focus points lower. It seems happy with more horizontal stretch than I think is necessary. 358-382 10 s then 5 s Trefoil pattern in PSF becoming visible. I think this is just the autofocus allowing us to see. 383-390 60 s losts guiding during obj_390 (perhaps obj_389) 391 10 s reacquire exposure Moved focus down by 20 units. PSF improved. So maybe the autofocus wasn't keeping up well. WTTM needed to be restarted. I took some check observations during that time. Restarted a 4x4x20" sequence 402 PTF12iiq 60 00:27 J 1.3 0.8 409-410 Unhappy with the autofocus. It's not making changes I would have made at the +- 20 units level. Turned off. Moved focus up by 15. Star looks better and more round. "Failed to acquire obj.411 after 3 tries. Skipping obj.411. click OK to continue." 410-416 PTF12iiq 60 00:35 J 1.3 0.75 421- SN2014J 10 Acquire and focus.
